1290044-41-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1290044-41-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,0,4 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1290044-41:
(9*1)+(8*2)+(7*9)+(6*0)+(5*0)+(4*4)+(3*4)+(2*4)+(1*1)=125
125 % 10 = 5
So 1290044-41-5 is a valid CAS Registry Number.
